Driving with a Trailer

Your vehicle is primarily intended for transporting people and luggage. However, if you drive with a trailer, follow the technical requirements, operating instructions, driving tips, and legal regulations.

Driving with a trailer affects the vehicle’s energy usage, performance, and wear, and it requires greater concentration from the driver.

A retrofitted trailer hitch must be installed according to the manufacturer’s instructions.

Warning

Do not transport any people in a trailer due to the risk of fatal injury.

Towing Capacity

Your vehicle can only be operated with class 1 or class 2 trailers.

Load Distribution

Incorrect cargo load and distribution can negatively impact vehicle handling. Observe the following:

  • Store objects in the vehicle luggage compartment whenever possible.
  • The vehicle should carry the heaviest load and the trailer the lightest load.
  • Distribute trailer loads so heavy objects are close to the axle.
  • Secure all objects to prevent sliding.
  • Utilize the maximum permitted tongue weight if possible.

Speed

Adhere to legal speed limits and regulations applicable in the country where you are operating the vehicle.

Driving stability decreases as speed increases. Do not exceed the maximum legal speed, especially during unfavorable road, weather, or wind conditions, particularly when driving downhill.

Hills

When driving uphill or downhill, the vehicle and trailer may tilt or sway more than on level surfaces. If swaying occurs, stabilize the trailer by braking firmly and immediately.

Never attempt to straighten the vehicle and trailer by accelerating.

Downshift before driving on hills to utilize engine braking.

Exterior Lighting

Follow all legal lighting regulations for trailers applicable in the country of operation.

Before driving, check all trailer lighting equipment while the trailer is hitched.

The headlight range control automatically adjusts the headlight range.

Outside Mirrors

Ensure sufficient visibility behind the vehicle using exterior mirrors. Install additional mirrors if necessary and adjust them correctly. Follow local regulations regarding additional mirrors.

Engine Cooling System

Driving with a trailer increases the load on the engine and cooling system. Ensure sufficient coolant is available.

Engine Coolant Temperature

Monitor the coolant temperature display during high outside temperatures or when driving on long inclines. Shift to higher gears in a timely manner.

Tires

Set tire pressure on the vehicle for full load conditions as specified on the tire pressure label. Adjust trailer tire pressure according to the manufacturer’s specifications if necessary.

Both vehicle and trailer should be equipped with winter tires when driving in winter conditions.

Overrun Brakes

If the trailer is equipped with overrun brakes, they must be correctly adjusted and fully functional. When braking, apply gentle braking first, then brake more firmly to reduce jerking.

Warning

Constant braking can cause brake overheating, reduced braking performance, increased braking distance, or complete brake failure.

Note

Retrofitted attachments may cause damage, especially to the trailer hitch ball head. In case of damage, have the function checked by an authorized Audi dealer or service facility.

Tips

  • Block wheels with chocks when parking on inclines with a loaded trailer.
  • Audi recommends additional vehicle inspections if towing frequently.
  • Avoid towing during the vehicle break-in period.

Trailer Hitch

Introduction

Only use a trailer hitch with a removable ball hitch mount approved for your vehicle, trailer, and permitted trailer weight.

Never mount a trailer hitch on the bumper. The hitch must not impair bumper function or require modifications to the exhaust or brake systems.

Check regularly that the trailer hitch is securely mounted and follow the manufacturer’s instructions.

Trailer Brakes

If the trailer has its own brake system, follow the manufacturer’s specifications. The trailer brake system must never be connected to the vehicle’s brake system.

Safety Chains

Ensure safety chains are correctly attached. They must allow cornering without touching the ground.

Warning

If the trailer is equipped with electronic brakes, they cannot be activated by the factory-installed control system, which increases the risk of an accident.
